Tribological studies and Microstructural characterisation of SiC and Fly Ash Particles Based Aluminium 2024 alloy Composites Prepared through Stir Casting Route

Aluminium and its alloys have excellent characteristics such as low density, high ductility and appropriate strength. In the marine, automotive and high-speed train sector, they find extensive applications. The volume percentage of metal matrix and reinforcement material and also the method of manufacturing the composites are the vital factors in making composite product. Composites of a metal matrix (MMCs), such as SiC and Al strengthened fly ash particles, are most widely used because of their excellent high hardness, high strength, corrosion resistance, stiffness and wear properties. The high strength and rigidity of AA 2024 alloys are well known. The high specific strength of such alloys with suitable reinforcement gives better yield properties and finds various applications at a reasonable cost. This article includes the study on mechanical and microstructural behaviour of AA 2024 metal matrix composites by reinforcing SiC and fly ash particles.
